Bugs in Phal(s)

[ldk]

Hello everyone. I am not new to the Forum, but have not had Phal questions in a long time. Recently I re-potted all of my Phals, about 20. A couple of them are a bit ill so I am nursing them along. The rest are in great shape. When I watered the other day, 1 Phal spewed hundreds of tiny light tan colored insects when the water hit them. They just boiled out of the pot and went everywhere. I don't know what the bugs are and how to get rid of them. I am afraid I will soon have these things in all of my orchids. It seems impossible to try to take a picture since they are so tiny. Thanks for any help or suggestions you may have.
